LIQUID-DIsIENsING APPARATUS.

E and State of New York, have invented cerf tain .new and useful Improvements in Liquid-Dispensing Apparatus, of which the following is a specification. y

My present inventionrelates to liquid disand more particularly to such apparatus as is usedin dispensing drinks which. are made up of -a flavoring syrup and a liquid, such as water under pressure, preferably drawn simultaneously.

l5 The main 'object of the invention iste dispensing apparatus of this type which will-positively deliver a drink such as water anda lavoring' syrup of the same 4constituency underyariations of pressure ofthe liquid used.-

A. further object isto so construct the apparatus that the constituency of the drinks Y can be' changed t'o anydesired degreeand the: changed .condition will remain the same under yariations of pressure.

In liquid dispensing apparatus, when itis 4desiredto dispense flavored drinks such as are madeup of carbonated water, or ordinarywater under pressure, and a flavoring provide a liquid is. employed. In one, the operator first draws the syrup and then ,adds the water, leaving 'entirely within his control the vcharacter of the drink; while in the other, the

l flavoring syrup and water are both drawn r simultaneously, in which latter operation,

- the character of the drink is not within his control. In the latter case the pressure of the charged water, or liquid under pressure, varies from time to time and therefore the drink `will contain more or less of this liquid as the case may be and its constituency correspondingly varies.' Further if left to the control of the operator to make allowance* for thevariations in pressure, the different drinksdrawn will not be uniform..

By my invention, in its preferred form, i

I provide a gage' in the pipe connection for the pressure water and a regulator which controls the ,amount of liquid under pressure which flows to the dispensing faucet; This regulator is so constructed that with a certain size openin and the liquid at a given pressure, a de ite amount of liquid will be delivered Ainto the drinking Specicationof Letters IPatent.

glass, .fort instance, 8 ozs. in 5 seconds. I a1so provlde a scale which coperates with an indicator secured tothe regulator and whlch is graduated to pounds pressure to correspond with the indications on the gage 6'0 and by means of which it is known that, ifthe lndicator on the gage stands at 80 lbs. and the indicator on the regulator is turned to 80I on thel scale, the regulator is opened a sufliclent amount'to deliver 8 ozs. yof water 65 1n. 5 seconds. If the pressure drops 'to 60 lhs. as shown on the gage, the indicator on the. regulator is turned to on the scale, whlch opens the valve in the regulator wider and 8 ozs. of water is still delivered 70l in 5 seconds. The flow of `syrup is delivered lnto the drinking glass at a uniform rate, whlch does not vary,according to the size of the passage through which it is delivered so that the amount of syrup delivered is always uniform, which amount is usually 1 oz. in 5 seconds.

' I n the apparatus which will be herein descr1bed,`the graduations on the scale are de- Itermined by the pressure, the size of the 30 opening through which the liquid iows and thepitch of the screw thread on the valve stem.

If it is desired to vary the constituency ofthe drink, that is make it more or less sweet,v means are provided whereby the scale can be shifted so that if the indicator on the regulator is set at the pressure mark, more or less water will be delivered than before, but nevertheless, each drink drawn at this new proportion will be the same.

My invention consists in a liquid dispensmg apparatus to which liquid under pressure and a syrup is delivered and means whereby drinks of uniform constituency will be delivered under variations of pressure of the liquid. y

My invention also consists in the combinations of parts and details of construction hereinafter more particularly described and then specified in the claims.

In the accompanying drawings which illustrate my invention as applied to a liquid dispensing apparatus in my preferred form adapted to deliver a avored drink, .Figure 1 is a general diagrammatic view,

partly in section, of an apparatus to which my invention is applied. Fig. 2 is a plan view'of apart thereof. Fig. 3 is .an en- 110 `ing faucet. 4 is a similar section, the

described as carriedinto effect in a liquid dispensing apparatus in which a flavored beverage such as a syrup and carbonated or other water under pressure, is delivered, it will be understood that this use is but one part thereof, and it is capable of use for dispensing other mixed drinks .without departing from the spirit of my invention.

1 indicates a source of liquid under pressure such as carbonated water or ordinary city water and 2 indicates a container within which is located a coil of pipe 3. vThe container 2 forms a cooling chamber within which ice may be packed if desired, to surround and cool the various liquid receptacles and conduits located therein. The coil 3 is connected tothe source of supply by pipes or conduits 4, the liquid under pressure being delivered to the coil and finally through a` pipe 11 to a dispensing faucet 5 located on the outside of the container 2. l A

6 indicates a suitable valve in the pipe 4 for shutting off the supply to the coil 3, and 7 indicates an ordinaryl pressure gage toindicate the pressure of the liquid fed to the coil 3.

The syrup supply is contained in a tank 8 which is always kept lled to the same level from a source 9 onthe principle of the inver'ted bottle. A suitable opening in the bottom of the tank 8 is connected to the faucet by a pipe or conduit 10 through which the syrup vis supplied under a constant pressure rendered so by the fact that the tank'f8 is always kept filled to the same level, this structure and principle being well understood. f

The preferred form of dispensing faucet comprises a disk 12 turning on a seat 13 formed in the main body portion 5 of the faucet, said disk being provided with a suit,- able operating handle 14 secured to the stem 15 to which the disk 12 is secured. The seat 13 is provided with a, compressible substance 16 upon which the disk 12 turns.

or passages communicating with the connecting pipes from the sources of liquid and syrup supply. A port 17 communicates with the pipe 11 for the liquid under pressure and a port or passage 18 communicates with the syrup (pipe 10.

. 19 indicates the mixing chamber closed by a cap 20 and is provided with an outlet or spout 21. A port 22-in the valve disk 12 is adapted'to register with the port or pas-' sage 17 in the valve seat 13 and establishv v t While my invention is herein shown and y drawn, which is always a as shown on the gage, then turned to on the scale, which opens 130' communication between the source of liquid ed to register with the port or passage 18 in the valve seat and establish communicac tion between the syrup supply and the mix- 3ing chamber. The size of the port 23 determines the amount of liavoring syrup fixed quantity and in the present instance 1 oz. in 5 seconds. The ports 22 and 23 are adapted to register with the passages 17 and 18 simultaneously so that the pressure liquid and syrup will be drawn at the same time, suitable stops Y being provided-to limit the movement of the valve disk in one direction when the ports are registered and in the other direction when they are closed, as well-known in the art. Y

To allow for variations in the pressure ofthe liquid delivered to the faucet erom the source 1, regulating means are pro ided at any suitable part of the apparatus vs `ereby the said means will operate preferably on the pressure liquid supply faucet and present a larger or-smaller passage for the flow of liquid. In the present instance the regulator is preferably secured to the dispensing faucet 5 and preferably operates on the pressure liquid passage 17 therein. The passage17 is provided with a valve seat 24v which is engaged by a suitable shoulder or valve formed on the end of a threaded spindle 25 which ,passes laterally through the body of the faucet andl is provided with a cap 26 on its outer end. The valve spindle 25 is suitably packed to prevent leakage and engages or disengages the valve seat 24, presenting a passage of greater or less size for the flow of liquid to the mixing chamber of the faucet by turning the spindle 25 in one direction or the other.

27 indicatesa plate preferably secured to the faucet body at or near the cap 26 of the spindle 25. lThe plate is preferably made semicircular and`is, provided with a scale graduated to indicate pounds pressure to correspond with the pressure gage 7. An indicator arm 28 secured to the spindle cap 26 moves over the scale on the plate 27 as the spindle 25 is rotated to increase or diminish the size of the opening between the valve seat 24 and the end of the spindle 25, The faucet body 5 is provided with ports `pressure of the liquid supplied is 80 lbs. as

shown on the pressure gage 7, the indicator 28 is placed at 80 on the scale 27 and the' opening in the passage 17 is sufficient to per- -mit say 8 ozs. of water in 5 seconds to pass through. Should the pressure drop to 60 the indicator arm is the passage wider and still 8 ozs. of water are delivered in seconds. As a constant stream of syrup is supplied say 1 oz. in 5 q seconds, determined by the size of the port 28 in the valve disk .or by other means if desired, the constituency of the drinks will always remain the same, no matter what the pressure may be, las the same amount of pressure liquid .is delivered per Iperiod of time under all pressures. l

If it is desired to make the drink sweeter,

I the indicator arm 28 could be kept at say 20 lbs. lower lthan `the pressure indicated on the gage 7 butv'this would be an unreliable and unsatisfactory way of accomplishing the desired result, as a clerk attending the apparatus would have to remember, if the pressure varied,l that he would always havey l to keep the indicator arm28` pointed'to 20 lbs. lower than the number of pounds indicated on the pressure gage. To avoid leaving the character of the drink tothe control of the operator, I mount the'plate'27 on its support. by a screw or other' fastener 29 which passes loosely through a segmental slot 30 in the plate 27 andfastens in the supg `reverse movement of the plate 27 is made,

the amount of advance or lead given. the plate determining the proportionsbf the drink.

The scale on the plate 27 is determined by considering the pressure,.the size -of vthe liquid passage-in the main valve disk and the pitch of the thread on the valve spindle 25. J
